Hi All,   I am building a new house.   Th= is house has no basement, but has a 24"? crawlspace under the house. &= nbsp; I have lots of time, to create a space for my three sensors, under th= e house.   I could also place them in the garage on the concrete = floor.   My thought was to enter the crawlspace, and dig a small = pit large enough to allow for elbow room, then line the pit with concrete b= locks to keep dirt away.  Perhaps covering the floor area similar= ly.  Concrete may not be the best material.   I could also p= our a pad or small footing using cement.

Please any thoughts on preparing this space?

 

Thanks, Ted
